No Peace for the Wicked is the first in the Riley Gavin/Frank Palmer series by Adrian Magson. It is free right now at Kindle US and UK. I haven't read any titles in this series, which looks (according to SYKM) as if it was his first series. But have I read and enjoyed some titles in his Lucas Rocco series (I'm a pushover for mysteries set in France), and also a couple in his Harry Tate series.

Spoiler:

The first in the Riley Gavin and Frank Palmer crime series.

When tough-minded female investigative reporter Riley Gavin is assigned to find out why two elderly ex-gangsters were murdered on the same day, she is surprised to find herself threatened with the same fate if she doesn’t back off.

But Riley doesn’t scare easily. And she never ducks an assignment. With the help of laid-back former Royal Military cop, Frank Palmer, she follows a bloody trail from the windswept south coast of England, through the lower reaches of south London, and finds herself facing a nasty death in Spain’s gangsters’ playground near Malaga. As she digs, she unearths a deadly web of vendettas, double-crosses and hatred in an underworld at war with itself.
The prize at stake for the killers is control of a criminal empire.

For Riley Gavin and Frank Palmer, failing could mean the difference between life or death.
